NOTES:
1. An unstabilized supply can be used.
2. VMOT = VP, all other inputs at 0V; all outputs at VP and IO = 0mA.
3. Switching levels with respect to MOT1, MOT2 and MOT3. See Figure 4.
4. Drivers are in high impedance OFF–state.
5. The outputs are short–circuit protected by limiting the current and the IC temperature.
6. Output transition time measurement. See Figure 5.
